🧭 Negative Feedback Loop

Circular diagram showing the negative feedback loop: normal level in centre, deviation upward triggers receptor detection, signal sent to coordination centre, effector produces response that brings level back down; deviation downward triggers opposite corrective response

Figure 1: The negative feedback loop — any deviation from normal triggers a corrective response in the opposite direction.

Note the key feature: the arrows always point back toward the centre (the normal level). The response is always in the opposite direction to the deviation. This is what makes it negative feedback.

Quick Recall Flashcards

What is homeostasis?
The maintenance of a stable internal environment despite changes in external conditions. The body regulates temperature, blood glucose, and water balance.
What is an effector?
An effector carries out the response to restore normal conditions. Effectors are muscles (contract) or glands (secrete hormones or other substances).
